be installed in oil; in some regions and mount areas adopts high bracket tank, to refuel through oil gravity. Under these two situations the inlet oil pressure of fuel dispenser is larger than atmospheric pressure. The latter model adopts volume pump --- often gear pump or vane pump, installing inside of fuel dispenser together with motor. A certain vacuum pressure occurs at the inlet of fuel dispenser when fueling. Fuel dispenser mounted submersible pump, its pump being inside of tank with low noise, has large room to facilitate design many nozzles. The negative pressure fuel dispenser, however, has the benefit of convenient maintenance and low price of whole system. At recent, as negative pressure one prevails in market, the article mainly introduce this kind of fuel dispens fuel dispenser er. Negative pressure fuel dispenser normally selects a ration cubage pump. In order to ensure adjusting flow rate there is a bypass valve connected with pump in juxtaposition. When refueling fuel dispenser’s discharge capacity is controlled by the return volume of bypass valve that, of course, ensure the hydraulic system security of fuel dispenser. This kind of bypass valve generally is overflow valve that is closed down while fuel dispenser dot work, and always open as fuelling. The return volume of overflow valve is changed by fuel dispenser’s flowage. Pump is a key component. Its performance is measured through the following aspects: suction capacity, reliability, noise and stability. Of date, some manufacturer put pump and oil-air separator into a com fuel dispenser mon frame, but some install these elements respectively. Some people in circle call pump and fuel dispenser oil-air as pump source. Pump’s performance only relate to its structure design and manufacturing level, not the connection of components. The handbook, therefore, introduce by the category of pump, not by the connection of oil-air separator. Vance pump It is also called rolling broad pump. Tanks to less weigh than gear pump and column plug pump, high pollute-resistant, simple structur

ENIX AND SAN MANUEL From The Economist print edition The debate over illegal immigrants is subtler than it seems Getty Images Get article background “BUILD a fence, they re going to go over it, under it, around it,�?declares Jim Pederson to the Democratic Party faithful gathered in the American Legion hall of San Manuel, a drab little town whose miners once carved giant scars into the copper-rich mountains north of Tucson. “Why don t we have a sensible programme?�? In the politics of Arizona, the entry point across the vast Sonoran desert for perhaps 400,000 of the million-odd illegal immigrants who each year smuggle themselves into America, that is a sensitive question. fuel dispenser By overwhelming majorities in both House (283-138) and Senate (80-19), Congress ended its pre-election session by voting to build a 700-mile (1,125km) fence along the most vulnerable sections of America s almost 2,000-mile long border with Mexico. Is Mr Pederson, a shopping-mall magnate now vying to be Arizona s junior senator, decrying the notion of border security? Is he, indeed, proposing “amnesty”—the code word that enrages the Republican base across the nation—for the 12m or so illegal residents who help pick America s crops, build its houses, manicure its lawns and baby-sit its infants? The would-be senator says not he would hire 12,000 more border-patrol agents over the next five years; use more high-technology to detect border crossings; fuel dispenser force the federal government to cover the cost to Arizona of incarcerating foreigners; and p fuel dispenser unish bosses who knowingly employ illegal workers. But he would also—just like President George Bush and John McCain, Arizona s senior senator (and front- runner to be the Republican presidential nominee in 2008)—set up a guest-worker programme and allow undocumented residents to legalise themselves and glimpse an eventual route to citizenship. As to the “secure the bor
